Displaying a zeal for competition which seems incredible in today's litigious society, Porsche by the 1960s was encouraging its customers to take their cars racing. By 1970, Porsche had produced what was essentially an instruction manual, describing the steps to modify a production 911 to compete on the international level. This booklet, "Information Regarding Porsche Vehicles Used for Sports Purposes" specifically listed the factory parts as well as the techniques required to prepare a 911 for circuit racing or international rally competition. Paired with the "Sports Purposes" manual was a secondary booklet entitled "Spare Parts List" which contained all of the special parts for the 911S to be reconstructed as a competition car, or "S-T" as they were called by the factory racing department.

1970 brought about a major change in engine displacement for the 911. From its introduction, the 911 had used a 2-liter engine with great success. This was now increased to 2.2-liter. This additional engine volume combined with the 9.8:1 compression ratio made the 2.2 S a spectacularly responsive package. Later 911's would grow to 2.4 liters and beyond, but with a lower compression ratio. Many experts feel that the 2.2-liter S was the best compromise of drivability and purity in the early S series.

The Motorcar Offered

Porsche 911 S #9110301014 is a perfect example of a competition minded owner ordering the top-of-the-line production 911S, equipping it with several racing influenced options, and then likely using the "Sports Purposes" and "Parts List" manuals to build his own 911 S-T.

This particular 911S was ordered and delivered to Fa. Hahn in Stuttgart, Germany. It was first registered to M & K Buehl GmbH, a jewelry wholesaler based in Ulm. A son of the Buehl family, Guenther Buehl had already established himself as a racer, driving a 2-liter 911 with some modest success. This new 2.2-liter 911 S was said to have served not only as a racing car, but also as Guenther's regular transportation, possibly explaining the unorthodox combination of an electric sunroof and radio/antenna with a roll bar and Recaro sports seats.

More interesting than the listed options is a common option not shown on the factory documentation. In a service bulletin dated 6/69, Porsche stated that the 911 S for 1970 would be "supplied in standard form with simplified equipment". It went on to state, "The vehicle Type 911 S with simplified equipment will not be exported to the United States". Buyers who wanted a more luxurious interior, better heating and more insulation, or anyone in the U.S. market, would end up with the option "Comfort Equipment for 911". This option is not listed for #9110301014. Those who opted for the "simplified S" were very few. This very rare lightweight version would have had its greatest appeal with people like Buehl...people who wanted to race.

Buehl's interest seems to have lain with long distance racing, the famed Nürburgring being a convenient outlet for this passion. The first race with 9110301014 came in April 1970 where he drove to a strong second place finish in the over 2,000cc GT class of the 300km race. In September, Klaus Rang and Hans Schuller were added as co-drivers for the 36-hour race at the Nürburgring. After more than 180 laps of the nearly 23 km course, Buehl, Rang and Schuller crossed the finish line in first place overall - a mighty achievement.

1971 offered two more long distance races at the Nürburgring, both ending with early retirement. These were the last two races for Buehl in the 911S. The car was then sold on to a Mr. K. Arzberger in Ulm and later to Mr. Mehmet Kose of Dusseldorf Germany. Near the end of the 1980's, the car passed into the hands of Methusalem Bernartz & Linke oHG in Siegburg. At this time, the color was changed from its original Conda Green to a dark blue before being sold on to Mr. Hanfried Bernartz, whose father was the founder of the Porsche Club Cologne in the 1950's. Mr. Bernartz recognized some of the unique sports-purpose features of the car which were confirmed in correspondence from Porsche in 1990.

Later, the car again changed hands to Mr. Michael Roock of Leverkusen, who performed a comprehensive restoration yet with a few deviations from original specification. Since this time, 9110301014 has been completely restored back to the original color and Group 3 specification. Most recently the car has been prepared for vintage circuit racing and looks much as it did back in 1970.

Offered with an extensive documentation file, this 911 is confirmed by Porsche factory documents as being a factory-built S/T with original optional equipment including sports seats and the rarely-seen-in-competition electric sunroof. Period photographs depict the car during its greatest triumphs at the Nürburgring, and its history is well understood. Complete with its original matching-numbers engine, this 911 is one of the most significant examples of a factory-prepared competition Porsche, and boasts a racing record that should make it eligible for the most prestigious international touring and vintage racing events.
